How to Use This Calculator

Enter water applied in inches and water beneficially used in inches for your system.
Set distribution uniformity (DU%) from catch-can tests or manufacturer specs.
Enter conveyance efficiency percentage for your delivery infrastructure.
Set field area in acres and number of irrigations per season for seasonal loss estimates.
Review Application efficiency (%), Scheduling coefficient, and Seasonal water loss (gallons) to identify improvement opportunities.
